Is it possible to pass command line arguments to a decorator in Django?

Question

I have a decorator that is supposed to use a parameter that's passed in from the commandline e.g

@deco(name)
def handle(self, *_args, **options):
    name = options["name"]

def deco(name):
    // The name should come from commandline
    pass

class Command(BaseCommand):
    def add_arguments(self, parser):
        parser.add_argument(
            "--name",
            type=str,
            required=True,
        )
    @deco(//How can I pass the name here?)
    def handle(self, *_args, **options):
        name = options["name"]

any suggestions on this?

You can make a "meta-decorator", something like:

from functool import wraps

def metadeco(function):
    @wraps(function)
    def func(*args, **kwargs):
        name = kwargs['name']
        return deco(name)(function)(*args, **kwargs)
    return func

and then work with that meta-decorator:

class Command(BaseCommand):
    def add_arguments(self, parser):
        parser.add_argument(
            "--name",
            type=str,
            required=True,
        )
    
    @metadeco
    def handle(self, *_args, **options):
        name = options['name']
        # …
